Operating Instructions EROCSCAN Pro 8.4 Connecting the cradle to the Printer Use the included printer connection cable to connect the cradle to the printer. Connect the appropriate end of the connection cable into the serial data port at the rear of the printer. Connect the opposite end of the data cable into the printer connector on the underside of the cradle (Figure 47). Place the two-position button located on the upper right of the top side of the cradle in the raised position for printer use (Figure 48) Figure 47 Figure 48 8.5 Printing with the Thermal Paper Printer Be sure the printer power is on and the button on the cradle is in the printer position. Place the instrument gently in the cradle. A printer icon should appear on the display and the test results should begin printing immediately. DPOAE Printout: Figure 49 shows a sample DPOAE printout from the thermal paper printer. The header shows the protocol name in the first line followed by the date/time of the test, test number, instrument serial number, probe serial number, and firmware version. Patient number is indicated or a blank line is provided to write in the name. (See section 8.7 for information on using numbered patients). The ear (Right or Left) and the test result (Pass or Refer) will be indicated on the printout.
